Completely depends on the job and the interviewers. For me personally, it is a big plus. Aside from the obvious reasons: * I can see candidates code quality * I don't penalize for sloppy code, but looks for examples of solid code / architecture / technical aptitude / comments I've had interviews where the candidate froze up and so I couldn't get enough data points, but I was able to use commits or blog posts from their open source history to augment by evaluation. I also double-check for copy/pasta to avoid giving them credit for code that is actually just a fork of another codebase.
